Abstract

　優れた防塵性を有しているとともに、０．１０～０．２０ｍｍといった更なる微小なクリアランスに対しても追従可能な優れた柔軟性を有する防塵材を提供する。 　本発明の発泡防塵材は、厚さが０．１～１．０ｍｍの発泡体により構成された防塵材であって、該発泡体が、平均セル径が１０～６５μｍの微細セル構造、０．１ｍｍの厚さに圧縮したときの対反発荷重が０．０１０～０．１００ＭＰａとなる特性、及び０．０１～０．０５０ｇ／ｃｍ3の見掛け密度を有していることを特徴とする。前記発泡体は、独立気泡構造又は半連続半独立気泡構造を有していることが好ましい。また、発泡体の片面又は両面に、粘着層を有していてもよい。該粘着層は、フィルム層を介して、発泡体上に形成されていることが好ましい。
